BIRAM C. DAVIS, OF BINGHAMTON, NEW YORK.

HAND-MACHINE FOR WIRING BLIND-RODS.

Specification of Letters Patent No. 25,726, dated October 11, 1859.

To all whom it may concern:

Be it known that I, BIRAM C. Davis, of Binghamton, in the county ofBroome and State of New York, have invented a new and useful Improvementon Machines for )Viring Blinds; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, in which Figure l is a perspectiveview of a hand machine for wiring blinds; Fig. 2, is a view showing themanner in which the blind rod is connected to the slats; and Fig. 3, isa view showing the adjustable arrangement for securing the window blindswhile operating in connecting the rods to the slats.

The operation of this machine is as follows: The blind is secured to theframe (K) by turning the crank (N,) which adjust-s the frame by means ofa rightand left-hand screw, which leaves the stationary bar (B,) in thecenter and thus connecting the rod (Q) in the center of blinds of anywidth. The machine Fig. l is then taken and the needle J passed througha trough containing the staples which thus picks them up in sutlicientquantities. The form A or machine is then placed over the rod C andstraddles the slat D, the lower claws of the form A being secured underthe blind by the stationary bar B, which thus brings the edge of theslat D and the eye of the staple in rod C into the proper aosition. Thejoint lever Gr is then rought down and the slide I opens the way for thestaples to pass in and is so constructed as to permit only one staple topass in at a time, which said staple is then passed through the eye ofthe staple in the rod C into the slat (D) connecting the rod to theslats as shown in Fig. 2 which is placed from one slat to the otherthroughout the whole length of the blind.

In setting the staples in the rods they are placed in the bed 0)-themachine is then placed straddle of the rod C and is secured by the lowerclaws to the gage F -said machine is moved from one notch or catch tothe other throughout the whole length of the rod. The screw M is for thepurpose of varying the staples to their proper depth. The spring (L)keeps the lever in a raised position.

Having thus described my invention as an improvement on other machinesof the same class, what I claim as new and improved is.

l. The set-ting form A which sets over the rod C and straddles the slatsD and which is secured under the blind by means of the stationary bar Bin such a manner as to set the staples through the eye of the staples inthe rod (C) into the slats D, D, being the equivalent means employed forsetting the staples into the rod C in combination with the adjustablearrangements K operating substantially as described.

2. I claim, in combination with the form A, the joint lever G, flangerod or driver (I-I), dividing slide I, inclined needle bar ,-the wholebeing arranged substantially as described and for the purpose set forth.

Dated September 27th 1859.
